Serial No. 511,632.

To all whom it may concern Be it known that l, Prrniirrr Banner on Rooms, citizen of the French Jpublic. residing at Paris, in France, have invented a certain new and useful Apparatus for Making Fertilizer from Refuse h'laterial, of which the following is a specification.

This invention relates to an installation for the treatment of sewage and house refuse generally in order to convert such waste products into manure in the form of tremely tine, dried and sterilized powder .1- into combustible material. In the latter case the heat produced by burning the material is utilized and the sewage or refuse completely destroyed.

A construction of the installation according to this invention is illustratedlby way of example. in the accompanying (lisgranr matic drawings in which Figure 1 is a plan and Fig. 2 is a vertical longitudinal section through the line A B Fig. 1. Fig. 2 shows by a side view and a plan View one of the carts,

The sewage or refuse is broughtto the receiving room by carts 4.0, the removable body 4-1 of which is provided with a bottom with flap valves 42 opening" like those of anon-oscillating coal ship.

The material is carried on a mono 'ail mechanism toclosed "refuse receivers or driers 1 which communicate each by a lower discharge iopper 2 and through an opening 3 with a vertically sliding door or panel 4, with the charging hopper 8 of a crusher 6. The panels 4 are provided with balance weights which move in lateral guides, and regulate the discharge of the material to be treated on to a sorting table 7 arranged in front of a hopper 8 which communicates with the crusher 6 by the neck 5. The receivers 1 are fed from the dust boxes l which dust boxes are the bodies ll of the carts 40 after being removed, and which bodies are, as before mentioned, provided with bot-toms which open like flap valves as soon as they are released. Men standing -on a raised door 9 regulate the discharge of the sewage which moves toward the cr' hers arterialreduced to powder inthe crush-err. 6, is discharged into inclined lower screen'dmuns it) which are rotatable and in which the first screening; to separate the sewage converted into powder takes place. The powder falls on to the common conveyer 11, which circulates under the battery of drums correspondin to the battery of crushers. The material which is too coarse to pass through the screen-drums 10 is dis-- charged on to another common conveyor 12 terminating at a receiving pit 13. This arrangement of drums combined respectively with one crusher each, avoids,in large installations, the accumulation of non-converted material which takes place if a single drum is used for a whole batteryof crushers working in parallel, such accumulation resulting in the choking of the drum and a very imperfect screening. Moreover in the case of a single drum the inspection and attendance are not easy.

From the pit 13 the material is raised by a bucket chain 14 to a second battery of crusher-s. To that end the bucket chain discharges the said material on to a transverse conveyor 16 with a double chute, supplying two or more crushers 17'. The material treated in the crushers 17 is screened in drums 18 arranged under each crusher, the powder being discharged on to the con veyer 11, and the coarser material on to an other conveyer 19 discharging it into the pit 21 (Fig. 1'). The powder which. is to form manure, is discharged by thegeneral conveyor 11 into the pit 20 whereih moves an inclined conveyor 21, which carries the said powder to the drying installation. The powder is discharged by the conveyor 21 into a rotary distributor 23 which introduces it into towers or drying kilns with several floors. Each floor, which is separated from the adjoining ones by a horizontal screen 24, is provided with a rotatable hollow cone 25 on which the powder is spread.

Hot, gases from smoke fines are introduced into the lower portion of the tower 22 and, being drawn upward by an upper exhauster 26, bring about the drying and the sterilization of the powder, which in order to complete the sterilizing action is introduced into a second tower 22 in which it undergoes similar treatment. A conveyer 27 transfers the powder from the bottom of the first tower. This drying process is tocomplete the drying action which commenced with Patented Mar. 25, 1913.

the crushing, and has also for its object to destroy the micro-organisms that are liable to produce fermentation on contact with the air. This fermentation takes place in the manure usually prepared, and it was only possible to avoid such fermentation in an imperfect manner by carrying it in vessets or closed cars. According to this invention therefore, it new industrial result. is produced. ()an leaving the second tower, the dry powder is raised by a bucket chain 28 to the drum 29 where the screening is completed, and Where waste that cannothe utilized, separated. The drums 10, 18 and 529 are formed in the known manner, of cylinders of wire gauze, the meshes of which are about 2.; m/m. across,

All material not converted and discharged into the pit 2V, is raised by the hoist 30 and discharged again on, to a conveyer 31 feeding a battery of furnaces 32 in which it is completely destroyed. The heat .roduced is utilized, first of all for the boilers 83 in connection with the said furnaces and then by circulation in the drying kilns 22, for the complete conversion into manure of the powdered product.

The steam produced in the boilers 33, is utilized for generatin power in driving engines 34 used for lig iting or driving :t'ans, rotary distributors, conveyers, or other machinery.
